Ruby Weekly 122 is chock full of awesome stuff. If you use Ruby, read this!

Straight from Matz: "Since there still remain undefined corner case behavior in refinements, and the time is running out, I decided not to introduce full refinement for Ruby 2.0." More generally, there's a lot of debate going on around the role of refinements in Ruby 2.0 and whether they should even be included at all. Matz says a final decision is expected 'within a few weeks.'
